Percutaneous Epididymal
Sperm Aspiration (PESA) & Testicular Sperm Extraction
(TESE)
Since 1995, HRC fertility specialists have employed the
methods of recovering sperm known as PESA & TESE
from men with obstructive and non-obstructive azoospermia
with extremely promising results.
With the advent of ICSI, the previous
notion that sperm needed to go through the full length
of the genital tract before it is able to achieve fertilization
is no longer valid. Previously, obstructed azoospermia
has been treated with microsurgery. This required scrotal
exploration under general anesthesia. PESA is a non-invasive
method of sperm recovery and has excellent potential
for patients who have had a vasectomy
and do not wish to undergo reversal, or patients
who have had an attempted reversal which has failed.
This technique would also be applicable for patients
with congenital absence of the vas deferens, previous
infection with resultant occlusion of the epididymus,
and ejaculatory dysfunction due to multiple sclerosis
or diabetes. TESE is useful for men who have non-obstructive
azoospermia caused from maturation arrest disorders
and for patients in whom sperm could not be obtained
through the PESA procedure.
These techniques
are relatively simple, the equipment required is minimal
and the procedures are much less invasive than the previous
microsurgical approaches. The patient is able to return
to work either the same day or the following day without
significant risk of complications which more often may
follow the open surgical procedure. Since 1995, HRC
physicians have completed 100 IVF PESA/TESE procedures
with a sperm recovery rate of 92% and a pregnancy rate
of 45%.
Our fertility clinics have consistently produced exceptional success rates for IVF, donor egg, ICSI, PGD, and many other procedures. Visit our success rates page.
